The Electrocardiogram (ECG) is analyzed during MRI, but is restricted to R wave detection because of the Magnetohydrodynamic (MHD) effect, induced by the blood flow inside the B0 field. Emerging applications, such as MRI-guided cardiac surgery or intra-cardiac electrophysiology, requires a deeper ECG analysis.
